The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] The relevant technology usually involves stamping the wire mesh into shape using a stamping machine, and then welding it manually. Because there are many spot welding points and frequent welding times for the wire mesh, and the strength is high, the production efficiency of the wire mesh is low.

[0027] One embodiment of this application provides a welding machine, including a welding apparatus. The welding apparatus includes a welding frame, a positioning mechanism, a clamping mechanism, and a welding mechanism. The positioning mechanism is disposed on the welding frame and has a bearing position for bearing a first material and a second material to be welded. The clamping mechanism is disposed on the welding frame and cooperates with the positioning mechanism to press the first material toward the second material. The welding mechanism is disposed on the welding frame and cooperates with the positioning mechanism to weld the press-formed first material to the second material.

[0028] By cooperating with the pressing mechanism and the positioning mechanism, the first material can be automatically stamped towards the second material. By cooperating with the positioning mechanism and the welding mechanism, the stamped first material can be welded to the second material, so that the first material and the second material can be stamped and welded directly on one machine, reducing the labor intensity of personnel and improving production efficiency.

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0030] Please see Figure 1 One embodiment of this application provides a welding machine 100 for stamping and welding materials to be welded. In some embodiments, the material to be welded is a wire mesh.

[0031] In some embodiments, the welding machine 100 includes a support base 10, a welding device 20, and a protective cover 30. The welding device 20 is disposed on the support base 10 so that the overall position of the welding device 20 is raised by the support base 10 to facilitate manual operation.

[0032] For ease of description of the technical solutions in this application, the following definitions are provided: Figure 1 The directions shown are front, back, left, right, up, and down. The second direction Y refers to the welding machine 100 facing both the front and back, the first direction X refers to the width of the welding machine 100, and the third direction Z refers to the height of the welding machine 100.

[0033] The protective cover 30 has an inner cavity 31, in which the welding device 20 is located. The protective cover 30 is mounted on the support base 10 and covers the welding device 20. The protective cover 30 has an operation port 32, which is located at the front of the protective cover 30 to facilitate manual handling of materials to be welded.

[0034] In some embodiments, sensors 33 are provided on the left and right sides of the operating port 32 to detect whether an object passes through the operating port 32. If the sensors 33 detect that an object (including but not limited to a human hand, robotic arm, etc.) has passed through the operating port 32, the welding device 20 stops operating, thereby improving the safety of the welding machine 100.

[0035] In some embodiments, sensor 33 is a photoelectric sensor.

[0036] Please see Figure 2 and Figure 3 In some embodiments, the welding apparatus 20 includes a welding frame 21, a positioning mechanism 22, a welding mechanism 23, and a clamping mechanism 24. The positioning mechanism 22 has a bearing position 2221 for bearing a first material and a second material. The clamping mechanism 24 is used to press the first material toward the second material and stamp it into shape. The welding mechanism 23 cooperates with the positioning mechanism 22 to weld the stamped first and second materials.

[0037] In some embodiments, the first material is steel wire mesh.

[0038] In some embodiments, the second material is a molded insert made of ferrous material.

[0039] By cooperating with the pressing mechanism 24 and the positioning mechanism 22, the first material can be automatically stamped towards the second material. By cooperating with the positioning mechanism 22 and the welding mechanism 23, the stamped first material can be welded to the second material, so that the first material and the second material can be stamped and welded directly on one machine, reducing the assembly work intensity of personnel and improving production efficiency.

[0040] In some embodiments, the welding frame 21 includes a base plate 211, a first side plate 212, a second side plate 213, a top plate 214, and a support plate 215. The first side plate 212, the second side plate 213, the top plate 214, and the support plate 215 are all disposed above the base plate 211.

[0041] The first side plate 212 and the second side plate 213 are arranged opposite each other along the second direction Y. The top plate 214 is arranged on the upper part of the first side plate 212 and the second side plate 213. The first side plate 212, the top plate 214 and the second side plate 213 constitute a gantry structure. The bearing plate 215 is fixed between the top plate 214 and the bottom plate 211.

[0042] Please see Figure 3 and Figure 4In some embodiments, the positioning mechanism 22 includes a pad 221. The pad 221 is fixedly connected to the support plate 215, and the second material 222 is disposed on the pad 221. The outer surface of the second material 222 away from the support plate 215 is the bearing position 2221.

[0043] In some embodiments, the support plate 215 is provided with a support groove 2151, and the pad 221 is at least partially disposed in the support groove 2151. On the one hand, this facilitates the positioning of the pad 221 and improves the ease of installation; on the other hand, the side of the support groove 2151 is used to limit the pad 221, thereby improving the positional stability of the pad 221.

[0044] In some embodiments, the pad 221 is detachably connected to the support plate 215 to facilitate replacement and maintenance of the pad 221.

[0045] In some embodiments, the pad 221 is provided with a plurality of first positioning bosses 2211, which are divided into two groups. The two groups of first positioning bosses 2211 are spaced apart along the first direction X of the welding machine 100. The second material 222 is stuck between the two groups of first positioning bosses 2211, thereby limiting the position of the second material 222 and improving the positional stability of the second material 222.

[0046] In some embodiments, the pad 221 is provided with a plurality of second positioning bosses 2212, which are divided into two groups. The two groups of second positioning bosses 2212 are spaced apart along the second direction Y of the welding machine 100. The second material 222 is stuck between the two groups of second positioning bosses 2212, thereby limiting the position of the second material 222 and improving the positional stability of the second material 222.

[0047] Please see Figure 3 In some embodiments, the clamping mechanism 24 includes a clamping drive 241 and a clamping plate 242. The clamping drive 241 is fixed to the welding frame 21, and the clamping plate 242 is located above the support plate 215. The clamping drive 241 has a telescopic rod 2411, and the clamping plate 242 is fixedly connected to the telescopic rod 2411. The clamping drive 241 drives the clamping plate 242 to move toward or away from the support plate 215 through the telescopic rod 2411.

[0048] In some embodiments, two sets of clamping drive members 241 are provided, with one set of clamping drive members 241 fixed to the facing surfaces of the first side plate 212 and the second side plate 213 respectively. The telescopic rods 2411 of both sets of clamping drive members 241 are connected to the surface of the clamping plate 242 away from the bearing plate 215 to improve driving stability.

[0049] Please see Figure 2 and Figure 5In some embodiments, the surface of the clamping plate 242 facing the second material 222 is provided with a contour groove 2421, which is used to cooperate with the second material 222, thereby forming a contour space between the outer surface of the second material 222 and the wall of the contour groove 2421.

[0050] When the clamping plate 242 separates from the support plate 215 by a certain distance, the first material is placed on the second material 222, thus completing the loading. The clamping plate 242 moves toward the support plate 215, pressing the first material onto the second material 222. At this time, the main body of the first material is located within the contouring space, thus completing the stamping of the first material.

[0051] Please see Figure 3 and Figure 4 In some embodiments, the positioning mechanism 22 further includes a positioning block 223. The surface of the pad 221 away from the support plate 215 is provided with a positioning groove 2213, and the positioning block 223 is movably disposed in the positioning groove 2213 in a direction toward or away from the support plate 215.

[0052] The second material 222 is provided with a relief groove 2222, and the positioning block 223 has an ejected state that passes through the relief groove 2222 and protrudes from the surface of the second material 222 away from the bearing plate 215. The positioning block 223 also has a retracted state that is simultaneously located in the positioning groove 2213 and the relief groove 2222.

[0053] In some embodiments, the positioning mechanism 22 further includes an elastic element 224, which is disposed between the positioning block 223 and the bottom wall of the positioning groove 2213. The elastic element 224 is used to drive the positioning block 223 to move in a direction away from the support plate 215 so that the positioning block 223 automatically resets, that is, switches from the retracted state to the ejected state.

[0054] In some embodiments, the elastic element 224 is configured as a compression spring. In other embodiments, the elastic element 224 is configured as a set of mutually repelling magnets.

[0055] Please see Figure 3 , Figure 4 and Figure 5 When the positioning block 223 is in the ejected state, the surface of the positioning block 223 away from the support plate 215 supports the first material. The clamping plate 242 moves toward the support plate 215, and the inner wall of the contour groove 2421 first presses the first material against the positioning block 223, thus initially positioning the first material. The clamping plate 242 continues to move toward the support plate 215, and the positioning block 223 gradually retracts into the positioning groove 2213 and the clearance groove 2222 until the positioning block 223 is in the retracted state. At this time, the main body of the first material is located in the contour space, thus completing the stamping of the first material.

[0056] Please see Figure 4 In some embodiments, the positioning mechanism 22 further includes a stop plate 225, which includes a stop body 2251 and a connecting portion 2252, with the connecting portion 2252 disposed on the side of the stop body 2251.

[0057] The positioning block 223 has a stop groove 2231 on its surface away from the bearing plate 215. The stop body 2251 is disposed in the stop groove 2231, and the bottom wall of the stop groove 2231 forms a block with the stop body 2251.

[0058] The stop groove 2231 is provided with a connecting groove 2232 along the second direction Y of the welding machine 100. The connecting part 2252 passes through the connecting groove 2232 and connects to the pad 221 to fix the relative position of the stop plate 225 and the pad 221. That is, the stop plate 225 and the pad 221 limit the upper limit stroke and the lower limit stroke of the positioning block 223, improve the problem that the positioning block 223 is pushed out of the positioning groove 2213 and the clearance groove 2222 by the elastic member 224, and improve the positional stability of the positioning block 223.

[0059] Please see Figure 3 In some embodiments, the welding mechanism 23 includes a welding drive 231, an insulating plate 232, and an electrode plate 233, all of which are located on the side of the clamping plate 242 away from the bearing plate 215.

[0063] In some embodiments, the pad 221 is connected to the positive terminal of the welding circuit, and the electrode plate 233 is connected to the negative terminal of the welding circuit.

[0064] In some embodiments, the electrode plate 233 is provided with a welding post 2331 facing the support plate 215, and the clamping plate 242 is provided with a clearance hole 2422. The welding post 2331 can pass through the clearance hole 2422 and be electrically connected to the first material and the second material 222, thereby welding the formed first material onto the second material 222.

[0065] In some embodiments, there are multiple welding posts 2331, and the multiple welding posts 2331 are arrayed on the surface of the electrode plate 233 facing the support plate 215. Multiple clearance holes 2422 are provided, and each clearance hole 2422 corresponds to one welding post 2331.
